The image forming method and image forming device

, (2007/10/08)
A developing device using a liquid developer removes developer using the contact-rotation between rollers such as a developing roller and thin layer forming roller when an image is not formed, and includes a contact pressure modification section that modifies the contact pressure in the contact region between rollers rotating in contact with one another. When operation is performed to remove the developer using the contact-rotation between rollers with the supply of liquid developer being suspended, modifications are made to ensure that the contact pressure in the contact region is smaller than that during image formation.

Novel 4H-pyrrolo[1,2-a][1,4]benzodiazepine derivatives of the formula STR1 wherein at least one of R1, R2 and R3 represent lower alkyl and the remainder hydrogen, R4 represents hydrogen or lower alkyl, ring A optionally contains at least one substituent selected from halogen, nitro and trifluoromethyl, and ring B optionally contains at least one substituent selected from halogen, nitro, trifluoromethyl, lower alkyl and lower alkoxy; and novel intermediates thereof expressed by the formula STR2 wherein Z represents protected amino. Compounds of formula (I) are prepared by subjecting compounds of formula (II) to protective group-elimination and cyclization. The compounds of formula (I) and acid addition salts thereof have useful anti-anxietic, sedative, anti-convulsant, muscle relaxant and hypnotic, and their toxicity is low.
